The former model, who is currently embroiled in a bitter divorce battle with The Beatles legend, is tired of being mocked and has branded certain media outlets "a**holes".
Heather's representative Michelle Elyzabeth fumed: "Heather married Paul McCartney, period. It's not going away.
"And during this divorce they (the media) will need access and are not going to get it. They are a**holes. There are limits and they make fun of her. They've crossed the line. They will be sorry."
Elyzabeth also claimed Heather, 39, was "joking" when she urged people to drink rats' milk to help save the planet.
She added to the New York Post newspaper: "She was joking about the rats. But she was serious about the milk. It is very bad for people, especially children. A cow can only give so much.
"Heather was furious over the way the rat story was reported. She told me, 'You can only take so much, then you become numb. Everything I do, people take it apart.' "
